Paying $700 a week in Perth rent? What buying a comparable Perth home actually costs

Perth renters have far more homes to choose from if they want to buy, but borrowing costs remain high. Kixstart Property tested 25 Perth property segments to see where buying an equivalent home is becoming financially competitive with continuing to rent.

Perth renters face an unusual housing market.

Finding a rental remains difficult. Yet buyers suddenly have far more homes to choose from.

REIWA recorded 7,312 properties listed for sale in Perth in the week ending 30 August 2026, compared with 2,981 in the same week a year earlier. Rental availability was much tighter, with 2,047 properties available for rent, compared with 2,233 a year earlier.

That raises an obvious question for someone paying $600, $700 or $800 a week in rent:

Would buying something similar now make financial sense?

Kixstart Property tested that question across 25 Perth property segments.

The answer is more complicated than comparing your weekly rent with a mortgage repayment.

More choice does not mean homes have become affordable

There is an important contradiction in Perth’s current market.

Buyers have considerably more choice than they had a year ago. Seller discounting has also increased. REIWA reported in June that about three in ten Perth houses were selling below their original listing price, compared with roughly one in ten during the tighter conditions of late 2025 and early 2026.

But that improvement in negotiating conditions has not fixed affordability.

The Housing Industry Association’s June-quarter 2026 Affordability Index put Australian housing at its least affordable level since HIA records began in 1994.

Perth recorded the largest deterioration among the capital cities over the year, with its affordability index falling 19.8 per cent. Higher interest rates combined with previous price growth have made mortgage servicing substantially harder even as market conditions have begun to soften.

A separate realestate.com.au affordability measure reached a similar conclusion nationally. A typical-income household could afford only 12 per cent of homes sold during 2025-26, the lowest share in the history of that index.

Cotality also estimated earlier this year that the household income required to service a median Perth house had risen by about $16,500 between January and May 2026 as higher rates combined with rising prices.

So Perth renters considering buying are facing two competing changes.

There are more properties to choose from.

But borrowing enough to buy one has become harder.

That makes the property type, purchase price and deposit increasingly important.

Buying is still generally more expensive month to month

At current borrowing costs, none of the 25 property segments Kixstart tested was cheaper to own month-to-month using a 10 per cent deposit.

Our modelling uses a representative 6.15 per cent owner-occupier principal-and-interest rate over 30 years and then tests higher-rate scenarios.

For context, advertised rates vary according to lender, loan-to-value ratio and borrower circumstances. Westpac, for example, currently advertises an online owner-occupier variable P&I rate of 5.99 per cent for qualifying loans at up to 80 per cent LVR.

Our ownership calculation also includes allowances for council rates, water charges, insurance, maintenance and strata costs where applicable.

For houses, the gap was often substantial.

A typical three-bedroom house in Rockingham, for example, had a purchase price around $820,000 against comparable rent around $600 a week in our dataset.

Under our assumptions, renting remained considerably cheaper than owning.

The same broad pattern appeared across many three-bedroom house markets.

So the fact that Perth now has more properties for sale does not automatically mean buying has become financially superior to renting.

Units tell a different story

The gap becomes more interesting when we look at some two-bedroom units, villas and townhouse-style properties.

In Belmont, our analysis used a representative two-bedroom purchase price around $592,000 and comparable rent around $762 a week.

With a 10 per cent deposit, estimated total ownership costs were about $3,900 a month.

Equivalent rent was about $3,300 a month.

Buying was therefore still roughly $600 a month more expensive.

But that is a considerably closer financial decision than many of the house comparisons.

Hamilton Hill produced a similar result.

A representative two-bedroom purchase price around $563,000 compared with rent around $695 a week. Estimated ownership cost with a 10 per cent deposit was about $3,686 a month, compared with rent of approximately $3,012.

Again, buying did not win on immediate cash flow.

But the difference was small enough to justify looking beyond the first month’s numbers.

A bigger deposit changes the calculation

At a 20 per cent deposit, the gap narrowed considerably.

Our Belmont example moved to approximately $193 a month more to own than rent.

Hamilton Hill moved to approximately $285 a month more.

That does not make buying automatically better.

It means the financial difference has become small enough that other questions become important.

How long do you expect to stay?
How important is tenure security?
Does the property have good resale demand?
What are the real strata costs?
Can you comfortably absorb higher interest rates?
How much of your available cash would buying consume?
What else could that deposit have been doing if it remained invested?

What if mortgage rates rise again?

A comparison that only works at one interest rate is not particularly useful.

Kixstart therefore stress-tested the strongest markets at the current modelling rate and at 0.25, 0.50 and 1.00 percentage points higher.

These are stress scenarios. They are not interest-rate forecasts.

For the Belmont two-bedroom example with a 10 per cent deposit:

at 6.15 per cent, estimated ownership cost was about $3,904 a month;
at 6.40 per cent, about $3,991;
at 6.65 per cent, about $4,079;
at 7.15 per cent, about $4,257.

Equivalent rent was approximately $3,302 a month.

The ownership premium therefore increased from roughly $602 a month at the base rate to about $955 a month under the one-percentage-point stress scenario.

Hamilton Hill showed the same vulnerability.

Its estimated ownership premium increased from about $674 a month at 6.15 per cent to around $1,010 a month at 7.15 per cent.

Thornlie’s two-bedroom example moved from roughly $808 to $1,117 a month.

Cannington moved from approximately $937 to $1,300.

That is why none of these markets should be described as an obvious financial win for buyers.

Some are becoming competitive.

They remain sensitive to borrowing costs.

First-home-buyer assistance helps with one problem, not every problem

Western Australia’s current first-home-buyer transfer-duty concession can materially reduce upfront purchasing costs.

For eligible transactions entered into from 7 May 2026, the WA Government increased the thresholds applying to the First Home Owner Rate.

The Australian Government’s 5% Deposit Scheme can also allow eligible first-home buyers to purchase with a smaller deposit without paying lenders mortgage insurance, subject to scheme and lender requirements.

These policies can materially reduce the amount of cash required to enter the market.

But a smaller deposit usually creates a larger mortgage.

That means someone can overcome the deposit hurdle while still facing a considerably higher monthly housing cost.

Those are two separate affordability questions.

What happens over ten years?

This is where the comparison becomes more interesting.

A mortgage repayment includes interest, but part of each repayment also reduces the loan principal.

Rent does not build property equity.

But a fair comparison also needs to give the renter credit for the money they did not put into a deposit, acquisition costs and higher monthly ownership expenses.

Kixstart therefore modelled several of the strongest markets over approximately five and ten years.

mortgage principal reduction;
mortgage interest;
ownership expenses;
rent escalation;
buying and selling costs;
the opportunity cost of the deposit;
zero, 2 per cent and 4 per cent annual property-growth scenarios.

These are scenarios, not forecasts.

In Belmont, the buyer remained approximately $18,000 behind the renter after five years if the property experienced no capital growth.

After ten years, however, the buyer was about $23,000 ahead under our zero-growth scenario.

At 2 per cent annual capital growth, the estimated ten-year ownership advantage increased to about $149,000.

Hamilton Hill was approximately break-even after ten years under the zero-growth scenario and moved more clearly in favour of ownership under modest positive-growth assumptions.

Thornlie and Cannington required more help from either capital growth, time or a larger deposit before the ownership case became as strong.

The important point is not that prices must rise.

They may not.

The important point is that selected Perth markets can now approach long-term financial competitiveness without requiring an aggressive capital-growth assumption.

Principal repayment contributes to that result.

Strata can change everything

There is an important warning in these numbers.

Broad “unit” statistics can combine apartments, villas and townhouses.

Their ownership costs can be completely different.

A two-bedroom villa in a small complex with limited common property may carry relatively modest strata costs.

A similarly priced apartment with lifts, a swimming pool, underground parking and substantial shared infrastructure may carry thousands of dollars more in annual levies.

A looming special levy can change the calculation again.

So can building defects, waterproofing failures, poorly funded reserve accounts or expensive common-property repairs.

That is why an attractive purchase-price-to-rent ratio should be treated as a screening signal, not a buying decision.

Where the numbers currently look most interesting

Our current analysis identified two-bedroom properties in Belmont and Hamilton Hill as the clearest examples where the rent-versus-buy gap has narrowed.

Two-bedroom stock in Thornlie, Cannington and Midland also warrants closer property-specific investigation.

What these markets have in common is more important than the suburb names themselves.

moderately priced two-bedroom stock;
relatively high comparable rents;
units, villas or townhouses rather than detached houses;
purchase prices near first-home-buyer concession thresholds;
properties where strata costs remain manageable.

For an eligible first-home buyer, an older villa or townhouse around or below $600,000 can therefore be worth investigating.

If it sits in a small complex, has reasonable strata expenses and has scope for sensible cosmetic improvement, the property may warrant further feasibility work.

That still does not make it an automatic purchase.

So should you keep renting or buy?

For most Perth markets we tested, renting remains cheaper today.

That should not be hidden.

And Australia’s current affordability evidence is a useful warning against interpreting increasing listings as meaning housing has suddenly become cheap.

It has not.

Perth affordability has deteriorated sharply.

Mortgage rates matter enormously.

But the decision is becoming closer in certain property types.

A renter paying around $700 a week should therefore avoid two assumptions.

The first is that buying must be better simply because rent feels expensive.

The second is that buying cannot possibly stack up because Perth property prices have risen.

Neither assumption is reliable.

The useful question is much more specific:

“I’m paying $X a week in rent and have approximately $Y available as a deposit. What would buying a genuinely comparable property actually look like?”

That comparison needs to include the mortgage, transfer duty, strata, council and water charges, insurance, maintenance, holding period, interest-rate risk and the amount of cash you would need to commit.

Methodology

Kixstart Property analysed 25 Perth property segments using sales and rental evidence available in early September 2026.

Current market evidence was checked against REIWA, the Reserve Bank of Australia, government first-home-buyer information and current lender pricing.

Ownership-cost modelling includes principal-and-interest repayments and allowances for council rates, water charges, insurance, maintenance and strata where applicable.

The baseline financing model uses a representative 6.15 per cent mortgage rate over 30 years. Separate scenarios test rates 0.25, 0.50 and 1.00 percentage points higher.

Five and ten-year scenarios include mortgage principal reduction, ownership expenses, selling costs, rent escalation, deposit opportunity cost and multiple capital-growth assumptions, including zero growth.

These calculations are research scenarios rather than financial advice or property forecasts.

Individual properties can differ materially from suburb medians. Actual finance terms, strata costs, council and water charges, building condition and transaction costs should be checked before a property decision is made.
